[GIT PULL] SH Drivers Updates for v4.8

[GIT PULL] SH Drivers Updates for v4.8

[Simon Horman]

Hi Linus,

Please consider these SH drivers updates for v4.8.

I expect this to be my last pull request for these drivers as
it removes usage of them from Renesas ARM Based SoCs and my
co-maintenance of them.

The drivers are still used by some SH SoCs and listed under SUPERH
in the MAINTAINERS file.


The following changes since commit 1a695a905c18548062509178b98bc91e67510864:

[PATCH 1/2] drivers: sh: Stop using the legacy clock domain on ARM

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Since commits 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and
PM_GENERIC_DOMAINS for SoCs with PM Domains") and 2ee98234b88174f2
("arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM
Domains"), CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled
unconditionally for Renesas ARM-based SoCs. Hence the legacy clock
domain is no longer used on these SoCs.

Remove the related support code, and stop entering drivers/sh/ on ARM.
