+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.
