[PATCH v2 0/3] Remove clocks dependency from SCM driver

[Sarangdhar Joshi]

On earlier chiptsets (APQ8064, MSM8660, MSM8690, MSM8916,
APQ8084, MSM8974) crypto operations of TZ were depends on crypto
clocks controlled by users/clients. However on MSM8996 crypto clocks
control is handled internally in TZ itself. The current series of
patches handle this clock dependency in SCM driver.

Changes since v1:
- Added Rob's Acked-by
- Removed of_device_is_compatible check from probe (Stephen)
- Modified typecast to take care of 32-bit pointer

Sarangdhar Joshi (3):
  dt-bindings: firmware: scm: Add MSM8996 DT bindings
  firmware: qcom: scm: Remove core, iface and bus clocks dependency
  firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails
