Message-Id: <f1ba020af5076172c9d29006a747ccf40027fedc.1458840219.git.mschiffer@universe-factory.net>
From: Matthias Schiffer <mschiffer@universe-factory.net>

Subject: [PATCH] MIPS: ath79: make bootconsole wait for both THRE and TEMT
This makes the ath79 bootconsole behave the same way as the generic 8250
bootconsole.
Also waiting for TEMT (transmit buffer is empty) instead of just THRE
(transmit buffer is not full) ensures that all characters have been
transmitted before the real serial driver starts reconfiguring the serial
controller (which would sometimes result in garbage being transmitted.)
This change does not cause a visible performance loss.
In addition, this seems to fix a hang observed in certain configurations on
many AR7xxx/AR9xxx SoCs during autoconfig of the real serial driver.
A more complete follow-up patch will disable 8250 autoconfig for ath79
altogether (the serial controller is detected as a 16550A, which is not
fully compatible with the ath79 serial, and the autoconfig may lead to
undefined behavior on ath79.)

Subject: [PATCH 256/381] clk: bcm2835: pll_off should only update
CM_PLL_ANARST
bcm2835_pll_off is currently assigning CM_PLL_ANARST to the control
register, which may lose the other bits that are currently set by the
clock dividers.
It also now locks during the read/modify/write cycle of both
registers.

audio domain clocks")

Subject: [PATCH 257/381] clk: bcm2835: divider value has to be 1 or more
Current clamping of a normal divider allows a value < 1 to be valid.
A divider of < 1 would actually only be possible if we had a PLL...
So this patch clamps the divider to 1.
