      MIPS: ralink: Fix platform_get_irq's error checking · b6ab1a13
      Arvind Yadav authored
      The platform_get_irq() function returns negative if an error occurs.
      zero or positive number on success. platform_get_irq() error checking
      for zero is not correct.

      MIPS: Fix CPS SMP NS16550 UART defaults · 7e5e371e
      James Hogan authored
      The MIPS_CPS_NS16550_BASE and MIPS_CPS_NS16550_SHIFT options have no
      defaults for non-Malta platforms which select SYS_SUPPORTS_MIPS_CPS
      (i.e. the pistachio and generic platforms). This is problematic for
      automated allyesconfig and allmodconfig builds based on these platforms,
      since make silentoldconfig tries to ask the user for values, and
      especially since v4.15 where the default platform was switched to
      generic.
      
      Default these options to 0 and arrange for MIPS_CPS_NS16550 to be no
      when using that default base address, so that the option only has an
      effect when the default is provided (i.e. Malta) or when a value is
      provided by the user.

      MIPS: BCM47XX Avoid compile error with MIPS allnoconfig · dfe00495
      Matt Redfearn authored
      Currently MIPS allnoconfig with CONFIG_BCM47XX=y fails to compile due to
      neither BCM47XX_BCMA nor BCM47XX_SSB being selected. This leads the
      enumeration in arch/mips/include/asm/mach-bcm47xx/bcm47xx.h to be empty,
      and compilation fails:
      
      In file included from arch/mips/bcm47xx/irq.c:32:0:
      ./arch/mips/include/asm/mach-bcm47xx/bcm47xx.h:34:1: error: expected
      identifier before '}' token
       };
       ^
      make[2]: *** [scripts/Makefile.build:314: arch/mips/bcm47xx/irq.o] Error 1
      
      Fix this by ensuring that BCM47XX_SSB is selected if BCM47XX_BCMA is
      not. This allows us to select either system or both, but not neither.

      MIPS: AR7: ensure the port type's FCR value is used · 0a5191ef
      Jonas Gorski authored
      Since commit aef9a7bd ("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
