Subject: [PATCH] spi/bcm63xx: remove unused speed_hz member variable
speed_hz is a write only member, so we can safely remove it and its
generation. Also fixes the missing clk_put after getting the periph
clock.

Subject: [PATCH] MIPS: BCM63XX: merge bcm63xx_clk.h into bcm63xx/clk.c
All the header file does is provide the internal structure of clk,
which shouldn't be used by anyone except clk.c itself anyway.

Subject: [PATCH 1/7] MIPS: BCM63XX: remove duplicate spi register definitions
BCM6338 and BCM6348, and BCM6358 and everything after that share the
same register layout. To not have to redefine them for each new chip
and keep the code size small, only use the definitions for the first
chip with the certain layout.

Subject: [PATCH 3/7] MIPS: BCM63XX: rework chip detection
Instead of trying to use a correlation of cpu prid and chip id and
hoping they will always be unique, use the cpu prid to determine the
chip id register location and just read out the chip id.

Subject: [PATCH 3/3] MIPS: BCM63XX: select BMIPS4350 and default to 2 CPUs
for supported SoCs
All BCM63XX SoCs starting with BCM6358 have a BMIPS4350 instead of a
BMIPS3300, so select it unless support for any of the older SoCs is
selected.
All BMIPS4350 have only two CPUs, so select the appropriate default.

Enabling BOOT_RAW is mandatory to get a binary image (objcopy from ELF

by CFE on BCM63XX DSL platforms, but is going to be necessary to support
BCM63XX on Cable Modem chips such as BCM3368.

Subject: [PATCH 2/6] MIPS: BCM63XX: add support for BCM3368 Cable Modem
The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
in the existing code base is required to get it supported. This patch adds
support for the following on-chip peripherals:
- two UARTS
- GPIO
- Ethernet
- SPI
- PCI
- NOR Flash
The most noticeable difference with 3368 is that it has its peripheral
register at 0xfff8_0000 we check that separately in ioremap.h. Since
3368 is identical to 6358 for its clock and reset bits, we use them
verbatim.

From f3b3faafe7b5a1c07b12d18e96c36bc8a0eecaed Mon Sep 17 00:00:00 2001
From: Florian Fainelli <florian@openwrt.org>
Date: Tue, 18 Jun 2013 16:55:41 +0000
Subject: [PATCH 3/6] MIPS: BCM63XX: recognize Cable Modem firmware format
Add the firmware header format which is used by Broadcom Cable Modem
SoCs such as the BCM3368 SoC. We export the bcm_hcs firmware format
structure because it is used by user-land tools to create firmware
images for these SoCs and will later be used by a corresponding MTD
parser.

Subject: [PATCH 4/6] MIPS: BCM63XX: provide a MAC address for BCM3368 chips
The BCM3368 SoC uses a NVRAM format which is not compatible with the one
used by CFE, provide a default MAC address which is suitable for use and
which is the default one also being used by the bootloader on these
chips.

Subject: [PATCH] MIPS: BCM63XX: remove bogus Kconfig selects
Remove the bogus selects on USB-related symbols for 6345 and 6338, not
only we do not yet support USB on BCM63XX, but they also cause the
following warnings:
warning: (BCM63XX_CPU_6338 && BCM63XX_CPU_6345) selects
USB_OHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies
(USB_SUPPORT && USB && USB_OHCI_HCD)
warning: (BCM63XX_CPU_6338 && BCM63XX_CPU_6345) selects
USB_OHCI_BIG_ENDIAN_DESC which has unmet direct dependencies
(USB_SUPPORT && USB && USB_OHCI_HCD)
make[4]: Leaving directory `/home/florian/dev/linux'
Just get rid of these bogus Kconfig selects because neither 6345 nor
6338 actually have built-in USB host controllers.

Subject: [PATCH] MIPS: BMIPS: support booting from physical CPU other than 0
BMIPS43xx CPUs have two hardware threads, and on some SoCs such as 3368,
the bootloader has configured the system to boot from TP1 instead of the
more usual TP0. Create the physical to logical CPU mapping to cope with
that, do not remap the software interrupts to be cross CPUs such that we
do not have to do use the logical CPU mapping further down the code, and
finally, reset the slave TP1 only if booted from TP0.

Subject: [PATCH 2/3] bcm63xx_enet: split DMA channel register accesses
The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:
- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space
This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

Subject: [PATCH] bcm63xx_enet: add support Broadcom BCM6345 Ethernet
This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:
- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
which means that the helpers enet_dma{c,s} need to account for this
channel width and we can no longer use macros
- BCM6345 DMA engine does not have any internal SRAM for transfering
buffers
- BCM6345 buffer allocation and flow control is not per-channel but
global (done in RSET_ENETDMA)
- the DMA engine bits are right-shifted by 3 compared to other DMA
generations
- the DMA enable/interrupt masks are a little different (we need to
enabled more bits for 6345)
- some register have the same meaning but are offsetted in the ENET_DMAC
space so a lookup table is required to return the proper offset
The MAC itself is identical and requires no modifications to work.

Subject: [PATCH 05/10] MIPS: bmips: merge CPU options into one option
Instead of treating each flavour as an exclusive CPU to select, make
BMIPS the only option and let SYS_HAS_CPU_BMIPS* decide for which
flavours to include support.
Run tested on BMIPS3300 and BMIPS4350, only build tested for BMIPS4380
and BMISP5000.

Subject: [PATCH 02/11] MIPS: BCM63XX: add USB device clock enable delay to
clock code
This patch adds the required 10 micro seconds delay to the USB device
clock enable operation. Put this where the correct clock knowledege is,
which is in the clock code, and remove this delay from the bcm63xx_udc
gadget driver where it was before.

Subject: [PATCH 03/11] MIPS: BCM63XX: move code touching the USB private
register
This patch moves the code touching the USB private register in the
bcm63xx USB gadget driver to arch/mips/bcm63xx/usb-common.c in
preparation for adding support for OHCI and EHCI host controllers which
will also touch the USB private register.

Subject: [PATCH 04/11] MIPS: BCM63XX: add OHCI/EHCI configuration bits to
common USB code
This patch updates the common USB code touching the USB private
registers with the specific bits to properly enable OHCI and EHCI
controllers on BCM63xx SoCs. As a result we now need to protect access
to Read Modify Write sequences using a spinlock because we cannot
guarantee that any of the exposed helper will not be called
concurrently.

Subject: [PATCH 05/11] MIPS: BCM63XX: introduce BCM63XX_OHCI configuration
symbol
This configuration symbol can be used by CPUs supporting the on-chip
OHCI controller, and ensures that all relevant OHCI-related
configuration options are correctly selected. So far, OHCI support is
available for the 6328, 6348, 6358 and 6358 SoCs.

Broadcom BCM63XX SoCs include an on-chip OHCI controller which can be
driven by the ohci-platform generic driver by using specific power

configuration.

Subject: [PATCH 08/11] MIPS: BCM63XX: introduce BCM63XX_EHCI configuration
symbol
This configuration symbol can be used by CPUs supporting the on-chip
EHCI controller, and ensures that all relevant EHCI-related
configuration options are selected. So far BCM6328, BCM6358 and BCM6368
have an EHCI controller and do select this symbol. Update
drivers/usb/host/Kconfig with BCM63XX to update direct unmet
dependencies.

Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
driven by the generic ehci-platform driver by using specific power
on/off/suspend callbacks to manage clocks and hardware specific
configuration.

Subject: [PATCH 06/14] MIPS: BCM63XX: replace irq dispatch code with a
generic version
The generic version uses a variable length of u32 registers of u32/u64.
This allows easier support for longer registers without having to rewrite
verything.
This "generic" version is not slower than the old version in the best case
(= i == next set bit), and twice as fast in the worst case in 64 bits.

Subject: [PATCH 19/63] NET: bcm63xx_enet: move phy_(dis)connect into probe/remove
Only connect/disconnect the phy during probe and remove, not during any
open/close. The phy seldom changes during the runtime, and disconnecting
the phy during close will prevent it from keeping any configuration over
a down/up cycle.
