From mboxrd@z Thu Jan 1 00:00:00 1970 From: david@lechnology.com (David Lechner) Date: Sat, 20 Jan 2018 11:13:59 -0600 Subject: [PATCH v6 20/41] ARM: da830: add new clock init using common clock framework In-Reply-To: <1516468460-4908-1-git-send-email-david@lechnology.com> References: <1516468460-4908-1-git-send-email-david@lechnology.com> Message-ID: <1516468460-4908-21-git-send-email-david@lechnology.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This adds the new board-specific clock init in mach-davinci/da830.c using the new common clock framework drivers. The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Also clean up the #includes since we are adding some here.
