MIPS: AR7: ensure the port type's FCR value is used

2018-03-01T03:09:40Z

[ Upstream commit 0a5191efe06b5103909206e4fbcff81d30283f8e ] 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 Fixes: aef9a7bd9b67 ("serial/uart/8250: Add tunable RX interrupt trigger I/F of FIFO buffers") Signed-off-by: Jonas Gorski Cc: Greg Kroah-Hartman Cc: Yoshihiro YUNOMAE Cc: Florian Fainelli Cc: Nicolas Schichan Cc: linux-mips@linux-mips.org Cc: linux-serial@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/17544/ Signed-off-by: Ralf Baechle Signed-off-by: Sasha Levin

MIPS: AR7: Defer registration of GPIO

2017-12-07T02:20:02Z

[ Upstream commit e6b03ab63b4d270e0249f96536fde632409dc1dc ] 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.

MIPS: Restore init.h usage to arch/mips/ar7/time.c

2014-03-26T22:09:23Z

Commit 0046be10e0c502705fc74d91408eba13a73bc201 ("mips: delete non-required instances of include ") inadvertently removed an include that was actually correct. Restore it. Note that it gets init.h implicitly anyway, so this is largely a cosmetic fixup; no build regressions were caused by this.

Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.

mips: delete non-required instances of include

2014-01-24T21:39:56Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
