[PATCH v5 0/6] Add Amlogic meson8b clock gates

[PATCH v5 0/6] Add Amlogic meson8b clock gates

[Alexander Müller]

This patch series adds support for the Amlogic meson8b clock gates. The Amlogic
U-Boot disables most of them at boot. In order to enable ethernet, USB and other
components it's mandatory to enable the clock gates when loading the corresponding
drivers.

The meson8b clock gate support is based on the previous work done for Amlogic gxbb
currently available in clk-next.

Changes since v4:
  - Rebased to linux-clk/clk-meson-gxbb-ao branch

Changes since v3:
  - Include include/dt-bindings/clock/meson8b-clkc.h to prevent code duplicates

Changes since v2:
  - Added commit description for patch 2
  - Changed CLK_NR_CLOCKS macro to constant int
  - Moved back MESON_GATE macro to share it between gxbb and meson8b

Changes since v1:
  - Fixed GXBB spelling
  - Moved newly introduced CLKID defines to private header
  - Moved CLK_NR_CLKS define from DT binding to private header
  - Rebased to linux-amlogic/v4.7/integ making Kconfig select obsolete

Alexander M?ller (6):
  clk: meson: Rename meson8b-clkc.c to reflect gxbb naming convention
  meson: clk: Move register definitions to meson8b.h
  meson: clk: Rename register names according to Amlogic datasheet
  clk: meson: Copy meson8b CLKID defines to private header file
  gxbb: clk: Adjust MESON_GATE macro to be shared with meson8b
  meson: clk: Add support for clock gates

[PATCH v5 4/6] clk: meson: Copy meson8b CLKID defines to private header file

[Alexander Müller]

Only expose future CLKID constants if necessary. This patch
removes CLK_NR_CLKS from the DT bindings but leaves all previously
defined CLKIDs there to keep backward compatibility.

[PATCH v5 5/6] gxbb: clk: Adjust MESON_GATE macro to be shared with meson8b

[Alexander Müller]

The macro used gxbb_ prefix for clock definitions. In order
to share the macro between gxbb and meson8b, the prefix must
be moved to gxbb.c.

[PATCH v5 6/6] meson: clk: Add support for clock gates

[Alexander Müller]

This patch adds support for the meson8b clock gates. Most of
them are disabled by Amlogic U-Boot, but need to be enabled
for ethernet, USB and many other components.

[PATCH v5 0/6] Add Amlogic meson8b clock gates

[Michael Turquette]

Quoting Alexander M?ller (2016-08-27 10:40:48)
> This patch series adds support for the Amlogic meson8b clock gates. The Amlogic
> U-Boot disables most of them at boot. In order to enable ethernet, USB and other
> components it's mandatory to enable the clock gates when loading the corresponding
> drivers.
> 
> The meson8b clock gate support is based on the previous work done for Amlogic gxbb
> currently available in clk-next.

Applied all to clk-next, via the clk-meson-gxbb branch.

Kevin, feel free to (re)pull that branch. It will not be rebased. Note
that I merged the separate clk-meson-gxbb-ao branch into as well.

Regards,
Mike
