Subject: [PATCH 1/6] ARM: IMXRT: introduce is_imxrt*() macros and get_cpu_rev()
Date: Thu, 20 May 2021 16:10:13 +0200	[thread overview]
Message-ID: <20210520141018.2972320-2-giulio.benetti@benettiengineering.com> (raw)
In-Reply-To: <20210520141018.2972320-1-giulio.benetti@benettiengineering.com>

We need those macros to instruct drivers on how to behave for SoC specific
quirks, so let's add it as done for other i.MX SoCs.
