| H A D | clk-7xx.c | 9063ea46 Thu Sep 12 08:26:09 CDT 2019 Tero Kristo <t-kristo@ti.com> clk: ti: dra7xx: Drop idlest polling from IPU & DSP clkctrl clocks
The IPU and DSP remote processor cores and their corresponding MMUs on
DRA7 SoCs have hardreset lines associated with them and are controlled
by a PRCM reset line each. Any clkctrl enable/disable operations cannot
be checked for module enabled/disabled status independent of the reset
operation, and this causes some unwanted timeouts in the kernel and
unbalanced states for these clocks. These details should be handled by
the driver integration code itself.
Add the CLKF_NO_IDLEST flag to both the IPU and DSP clkctrl clocks so
that these module status checks are skipped.
