Stephen Boyd 059a1aa7eb clk: keystone: Remove clk.h include
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver.

Ivan Khoronzhuk a65e0c6a7f clk: keystone: gate: fix clk_init_data initialization
The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.

Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.

So initialize flags in this structure too.

Grygorii Strashko e0c223ec67 clk: keystone: gate: fix error handling on init
This patch fixes Keystone gate control clock driver initialization path:
1) clk_register_psc() returns error code and not a pure pointer, hence
its return value need to be checked using IS_ERR(clk) macro.

2) Mapped IO memory isn't unmapped in case of errors, hence fix it.

Santosh Shilimkar 7affe5685c clk: keystone: Add gate control clock driver
Add the driver for the clock gate control which uses PSC (Power Sleep
Controller) IP on Keystone 2 based SOCs. It is responsible for enabling and
disabling of the clocks for different IPs present in the SoC.
