[PATCH v5 0/2] Add platform clock for BayTrail platforms

From: Irina Tirdea
Date: Wed Dec 07 2016 - 10:44:42 EST


These patches specifically enable the audio MCLK required by Baytrail CR
devices. It is the remaining part of a bigger set of patches
(already merged in Mark's tree) that enable sound for Baytrail CR devices
(especially Asus T100TAF) [1]. They include the clock driver and a move
of the non-architectural pmc_atom driver code into drivers/platform/x86.

Changes from v4:
- move the pmc_atom driver from arch/x86/platform/atom to
drivers/platform/x86

Changes from v3:
- replace devm_kzalloc with devm_kcalloc
- add x86 architecture maintainers

Changes from v2:
- move clk platform data structures to a separate include file
- store clk_hw pointer for the fixed rate clocks

Changes from v1:
- register the clk device as child of pmc device
- pass iomem pointer from pmc driver to clk driver to avoid using
pmc_atom_read()/write() and use readl/writel API instead
- use devm_clk_hw_register/clkdev_hw_create instead of
clk_register/clkdev_create
