Deep enough power saving mode can result into losing context of the clock
registers also, and they need to be restored once coming back from the power
saving mode. Hence add functions to save/restore clock context.
Tested for DS0 on am437x-gp-evm
Based on top of linux-next
Resend Series:
* Rebased on top of Linux 4.19-rc2
* Added Tony's Ack.
Changes in v2:
* Renamed clk_dflt_restore to clk_gate_restore_context
Changes in v3: Corrected the e-mail address of linux-omap list
Keerthy (2):
clk: clk: Add clk_gate_restore_context function
ti: pm33xx: Save/restore clk context based on enable_off_mode setting
Russ Dill (2):
clk: clk: Add functions to save/restore clock context en-masse
clk: ti: Add functions to save/restore clk context
