Subject: [PATCH v2 0/2] qcom: ehci: enable core + iface clocks
Date: Mon, 06 May 2024 10:26:51 +0000	[thread overview]
Message-ID: <20240506-msm8916-hs-usb-clocks-v2-0-34f741b3a2ec@samcday.com> (raw)

These clocks are mandatory, as can be seen in msm_hsusb driver in the
Linux kernel.

The appropriate HS_USB AHB/SYSTEM clocks were added to gcc_apq8016.

Technically there's other adjacent SoC families that can use the
msm_hsusb driver with different clocks, but only msm8916/apq8016 are
currently making use of it so I think this change shouldn't break
anything elsewhere.

Changes in v2:
- Remove nonsensical/unnecessary reference to pending qcom debug dump
  from commit message.
- Collapse ftbl_gcc_usb_hs_system_clk into apq8016_clk_set_rate, since
  it's only 1 entry.
- Add bounds check on clock id in apq8016_clk_enable
- Add warn if a rate other than 80mhz is requested for
  GCC_USB_HS_SYSTEM_CLK
- Caleb: I opted to keep the non-bulk clock enablement code as-is in
  ehci_msm, since that more closely resembles the existing Linux
  kernel code.
- Link to v1: https://lore.kernel.org/r/20240502-msm8916-hs-usb-clocks-v1-0-eeccf483b68d@samcday.com
