Subject: [PATCH v2 0/2] CREG clk driver for NXP LPC18xx family
Date: Sat, 20 Feb 2016 19:53:35 +0100 [thread overview]
Message-ID: <1455994417-4471-1-git-send-email-manabian@gmail.com> (raw)
This patch set adds a clk driver for the low power clocks found in
the CREG block on lpc18xx. CREG is a collection of miscellaneous
configuration registers that can be accessed through a syscon
regmap interface. The clk driver makes it possible to setup and
enabled these two clocks.
This need to support peripherals like the internal RTC on the
lpc18xx platform.
Mike/Stephen is this what you envisioned?
It seems to work, but I currently don't have a setup that requires
the 32khz clock early so that part isn't really tested.
The probe deferral seems to work for the RTC:
[ 3.386861] lpc24xx-rtc 40046000.rtc: error getting rtc clock
[ 6.737615] lpc24xx-rtc 40046000.rtc: rtc core: registered lpc24xx-rtc as rtc0
Changes since v1:
- Split driver with one early init and one platform driver
probe.
Based on v4.5-rc1.
