      treewide: Switch printk users from %pf and %pF to %ps and %pS, respectively · d75f773c
      Sakari Ailus authored
      %pF and %pf are functionally equivalent to %pS and %ps conversion
      specifiers. The former are deprecated, therefore switch the current users
      to use the preferred variant.
      The changes have been produced by the following command:
      	git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \
      	while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done
      And verifying the result.

      ARM: imx: add i.mx6ulz msl support · c90dec00
      Anson Huang authored
      The i.MX 6ULZ processor is a high-performance, ultra
      cost-efficient consumer Linux processor featuring an
      advanced implementation of a single Arm® Cortex®-A7 core,
      which operates at speeds up to 900 MHz.
      This patch adds basic MSL support for i.MX6ULZ, the
      i.MX6ULZ has same soc_id as i.MX6ULL, and SRC_SBMR2 bit[6]
      is to differentiate i.MX6ULZ from i.MX6ULL, 1'b1 means
      i.MX6ULZ and 1'b0 means i.MX6ULL.

      ARM: imx: add suspend/resume support for i.mx6ul · ee4a5f83
      Anson Huang authored
      This patch adds suspend function for i.MX6UL, it supports
      "standby" and "mem" mode, for "standby" mode, SoC will
      enter STOP mode only, while for "mem" mode, SoC will
      enter STOP mode and DDR IO will be set to low power
      As i.MX6UL contains a "Cortex-A7" ARM core which has no
      PL310, so we need to avoid any PL310 operations during
      suspend/resume, also, we need to flush Cortex-A7's inernal
      L2 cache before suspend.

      genalloc: add name arg to gen_pool_get() and devm_gen_pool_create() · 73858173
      Vladimir Zapolskiy authored
      This change modifies gen_pool_get() and devm_gen_pool_create() client
      interfaces adding one more argument "name" of a gen_pool object.
      Due to implementation gen_pool_get() is capable to retrieve only one
      gen_pool associated with a device even if multiple gen_pools are created,
      fortunately right at the moment it is sufficient for the clients, hence
      provide NULL as a valid argument on both producer devm_gen_pool_create()
      and consumer gen_pool_get() sides.
      Because only one created gen_pool per device is addressable, explicitly
      add a restriction to devm_gen_pool_create() to create only one gen_pool
      per device, this implies two possible error codes returned by the
      function, account it on client side (only misc/sram).  This completes
      client side changes related to genalloc updates.

      genalloc: rename dev_get_gen_pool() to gen_pool_get() · 0030edf2
      Vladimir Zapolskiy authored
      To be consistent with other genalloc interface namings, rename
      dev_get_gen_pool() to gen_pool_get().  The original omitted "dev_" prefix
      is removed, since it points to argument type of the function, and so it
      does not bring any useful information.

      ARM: imx6: initialize CCM_CLPCR_LPM into RUN mode earlier · 35e2916f
      Shawn Guo authored
      Commit 4631960d26da ("ARM: imx6: set initial power mode in pm function")
      moves imx6_set_lpm() from clock init function into
      imx6_pm_common_init().  This causes a hang when cpuidle support is
      enabled.  The reason for that is ARM core clock is shut down
      unexpectedly by WAIT mode.  It happens with the following call stack:
      When wait_for_completion() is called as above, all cores are idle/WFI.
      Hence, the reset value of CCM_CLPCR_LPM - WAIT mode, will trigger a
      hardware shutdown of the ARM core clock.
      To fix the regression, we need to ensure that CCM_CLPCR_LPM is
      initialized into RUN mode earlier than cpuidle governor registration,
      which is a postcore_initcall.  This patch creates function
      imx6_pm_ccm_init() to map CCM block and initialize CCM_CLPCR_LPM into
      RUN mode, and have the function called from machine .init_irq hook,
      which should be early enough.

      ARM: imx6: set initial power mode in pm function · 8fb76a07
      Shawn Guo authored
      Rather than setting initial low-power mode in every single i.MX6 clock
      initialization function, we should really do that in pm code.  Let's
      move imx6q_set_lpm(WAIT_CLOCKED) call into imx6_pm_common_init().
      While at it, let's rename the function to imx6_set_lpm() since it's
      actually common for all i.MX6 SoCs.
