Date: Sun, 29 Oct 2017 15:50:42 +0100
Subject: [PATCH RFC 3/3] MIPS: AR7: ensure the port type's FCR value is used
Since commit aef9a7bd9b67 ("serial/uart/8250: Add tunable RX interrupt
trigger I/F of FIFO buffers"), the port's default FCR value isn't used
in serial8250_do_set_termios anymore, but copied over once in
serial8250_config_port and then modified as needed.
Unfortunately, serial8250_config_port will never be called if the port
is shared between kernel and userspace, and the port's flag doesn't have
UPF_BOOT_AUTOCONF, which would trigger a serial8250_config_port as well.
This causes garbled output from userspace:
[ 5.220000] random: procd urandom read with 49 bits of entropy available
ers
[kee
Fix this by forcing it to be configured on boot, resulting in the
expected output:
[ 5.250000] random: procd urandom read with 50 bits of entropy available
Press the [f] key and hit [enter] to enter failsafe mode
Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level

I'm not sure if this is just AR7's issue, or if this points to a general
issue for UARTs used as kernel console and login console with the "fixed"
commit.

Subject: [PATCH 1/3] MIPS: AR7: defer registration of GPIO
When called from prom init code, ar7_gpio_init() will fail as it will
call gpiochip_add() which relies on a working kmalloc() to alloc
the gpio_desc array and kmalloc is not useable yet at prom init time.
Move ar7_gpio_init() to ar7_register_devices() (a device_initcall)
where kmalloc works.
Fixes: 14e85c0e69d5 ("gpio: remove gpio_descs global array")

Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.
