      clk: qcom: HDMI source sel is 3 not 2 · c556bcdd
      Stephen Boyd authored
      The HDMI PLL input to the tv mux is supposed to be 3, not 2. Fix
      the code so that we can properly select the HDMI PLL.

      clk: define and export clk_debugs_add_file · fb2b3c9f
      Peter De Schrijver authored
      Define and export a new function clk_debugs_add_file which adds a file
      to a existing clock's debugfs directory. This can be used by clock
      providers to add debugfs entries which are not related to a specific clock
      type. Examples include the ability to measure the rate of a clock. It can
      also be used by modules to create new debugfs entries. This is useful if you
      want to expose features for testing which can potentially cause system
      instability such as allowing to change a clock's rate from userspace.

      Samsung clock fixes for v3.16.
      
      This pull request contains fixes for various issues found while testing
      -rc versions of Linux 3.16. Mostly two kinds of patches:
      
      * Fixes of incorrectly defined clocks
      
      1) a37c82a3 clk: samsung: exynos4: Remove SRC_MASK_ISP gates
      
          Issue present since v3.10.
      
      2) 0b1643b3 clk/exynos5250: fix bit number for tv sysmmu clock
      
          Issue present since v3.16.
      
      3) 44ff0254 clk: exynos5420: Remove aclk66_peric from the clock tree description
      
          Issue present since v3.11.
      
      * Adding things missed by original patches
      
      1) cec1cdea clk: samsung: fix several typos to fix boot on s3c2410
      2) 34ece9e6 clk: samsung: add more aliases for s3c24xx
      
          Both issues present since the driver was added in v3.16.
      
      3) a92dda4b clk: s3c64xx: Hookup SPI clocks correctly
      
          Issue present since v3.12.

      clk: s2mps11: Fix clk_ops · 89ed7e6e
      Karol Wrona authored
      s2mps11 clocks had registered callbacks for prepare ,unprepare and is_enabled.
      During disabling unused clocks the lack of is_prepared caused that unused
      s2mps11 clocks were not unprepared and stayed active.
      
      Regmap_read is cached so it can be called in is_prepare callback
      to achieve this information. Enabled field was removed from struct s2mps11_clk.

      When the main crystal frequency is not set, the main clock is approximated using
      the MAINF value in the CKGR_MCFR register. Warn the user in that case.

      clk: s2mps11: Fix double free corruption during driver unbind · 2a96dfa4
      Krzysztof Kozlowski authored
      After unbinding the driver memory was corrupted by double free of
      clk_lookup structure. This lead to OOPS when re-binding the driver
      again.
      
      The driver allocated memory for 'clk_lookup' with devm_kzalloc. During
      driver removal this memory was freed twice: once by clkdev_drop() and
      second by devm code.

      clk: Add driver for Palmas clk32kg and clk32kgaudio clocks · 942d1d67
      Peter Ujfalusi authored
      Palmas class of devices can provide 32K clock(s) to be used by other devices
      on the board. Depending on the actual device the provided clocks can be:
      CLK32K_KG and CLK32K_KGAUDIO
      or only one:
      CLK32K_KG (TPS659039 for example)
      
      Use separate compatible flags for the two 32K clock.
      A system which needs or have only one of the 32k clock from
      Palmas will need to add node(s) for each clock as separate section
      in the dts file.
      The two compatible property is:
      "ti,palmas-clk32kg" for clk32kg clock
      "ti,palmas-clk32kgaudio" for clk32kgaudio clock
      
      Apart from the register control of the clocks - which is done via
      the clock API there is a posibility to enable the external sleep
      control. In this way the clock can be enabled/disabled on demand by the
      user of the clock.

      clk: Fix build warnings · 6b44c854
      Sachin Kamat authored
      ‘all_lists’ and ‘orphan_list’ is accessed only when DEBUG_FS is defined.
      Thus, make their compilation conditional to fix the below warnings introduced
      by commit 27b8d5f7 ("clk: flatten clk tree in debugfs"):
      drivers/clk/clk.c:40:27: warning: ‘all_lists’ defined but not used [-Wunused-variable]
      drivers/clk/clk.c:46:27: warning: ‘orphan_list’ defined but not used [-Wunused-variable]

      clk: ppc-corenet: Fix Section mismatch warning · da788acb
      Jingchang Lu authored
      WARNING: drivers/built-in.o(.data+0x10258):
      Section mismatch in reference from the variable ppc_corenet_clk_driver
      to the (unknown reference) .init.rodata:(unknown)
      The variable ppc_corenet_clk_driver references
      the (unknown reference) __initconst (unknown)
      If the reference is valid then annotate the
      variable with __init* or __refdata (see linux/init.h) or name the variable:
      *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
