Subject: [PATCH V7 10/13] boot_constraint: Add support for IMX platform
Date: Fri, 23 Feb 2018 15:53:49 +0530	[thread overview]
Message-ID: <d422312bdcba54bb8d1c3c18b2b0e866c28e12ad.1519380923.git.viresh.kumar@linaro.org> (raw)

In-Reply-To: <cover.1519380923.git.viresh.kumar@linaro.org>

This adds boot constraint support for IMX platforms. Currently only one
use case is supported: earlycon. Some of the UARTs are enabled by the
bootloader and are used for early console in the kernel. The boot
constraint core handles them properly and removes them once the serial
device is probed by its driver.

This gets rid of lots of hacky code in the clock drivers.
