clk: at91: Fix a return value in case of error

2016-10-20T23:37:56+00:00

If 'clk_hw_register()' fails, it is likely that we expect to return an
error instead of a valid pointer (which would mean success).

Fix commit f5644f10dcfb ("clk: at91: Migrate to clk_hw based registration
and OF APIs")

clk: at91: sckc: optimize boot time

2016-09-21T00:03:04+00:00

Assume that if the oscillator is enabled (OSC32EN bit is present), the
delay has already elapsed as the bootloader probably waited for the
oscillator to settle. This could waste up to 1.2s.

clk: at91: Add sama5d4 sckc support

2016-09-21T00:02:58+00:00

Starting with sama5d4, the crystal oscillator is always enabled at startup
and the SCKC doesn't have an OSC32EN bit anymore.

Add support for that new controller.

clk: at91: move slow clock controller clocks to sckc.c

2016-09-21T00:02:38+00:00

Move all clocks related to the slow clock controller to sckc.c. This avoids
extern definitions and allows to remove sckc.h

clk: at91: Migrate to clk_hw based registration and OF APIs

2016-09-15T00:40:31+00:00

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

clk: at91: fix clk_programmable_set_parent()

2016-07-19T00:45:41+00:00

Since commit 1bdf02326b71e ("clk: at91: make use of syscon/regmap
internally"), clk_programmable_set_parent() is always selecting the
first parent (AKA slow_clk), no matter what's passed in the 'index'
parameter.

Fix that by initializing the pckr variable to the index value.

clk: at91: make of_sama5d2_clk_generated_setup() static

2016-06-21T00:44:33+00:00

The of_sama5d2_clk_generated_setup() is not exported outside
of the driver, so make it static to fix the warning about it
being not static:

drivers/clk/at91/clk-generated.c:270:13: warning: symbol 'of_sama5d2_clk_generated_setup' was not declared. Should it be static?

clk: at91: fix check of clk_register() returned value

2016-04-15T23:57:09+00:00

The clk_register() function returns a valid pointer to struct clk or
ERR_PTR() error code, this makes a check for returned NULL value
useless and may lead to oops on error path.

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

2016-03-23T13:06:45+00:00

Pull clk updates from Stephen Boyd:
 "The clk changes for this release cycle are mostly dominated by new
  device support in terms of LoC, but there has been some cleanup in the
  core as well as the usual minor clk additions to various drivers.

  Core:
   - parent tracking has been simplified
   - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
   - of_clk_init() doesn't consider disabled DT nodes anymore
   - clk_unregister() had an error path bug squashed
   - of_clk_get_parent_count() has been fixed to only return unsigned ints
   - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone

  New Drivers:
   - NXP LPC18xx creg
   - QCOM IPQ4019 GCC
   - TI dm814x ADPLL
   - i.MX6QP

  Updates:
   - Cyngus audio clks found on Broadcom iProc devices
   - Non-critical fixes for BCM2385 PLLs
   - Samsung exynos5433 updates for clk id errors, HDMI support,
     suspend/resume simplifications
   - USB, CAN, LVDS, and FCP clks on shmobile devices
   - sunxi got support for more clks on new SoCs and went through a
     minor refactoring/rewrite to use a simpler factor clk construct
   - rockchip added some more clk ids and added suport for fraction
     dividers
   - QCOM GDSCs in msm8996
   - A new devm helper to make adding custom actions simpler (acked by Greg)"
