From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vineet.Gupta1@synopsys.com (Vineet Gupta) Date: Tue, 2 Feb 2016 16:28:57 +0530 Subject: [PATCH 7/9] ARC: use fixed frequencies in arc_set_early_base_baud() In-Reply-To: <1454410739-24444-1-git-send-email-vgupta@synopsys.com> References: <1454410739-24444-1-git-send-email-vgupta@synopsys.com> List-ID: Message-ID: <1454410739-24444-8-git-send-email-vgupta@synopsys.com> To: linux-snps-arc@lists.infradead.org From: Alexey Brodkin UARTs usually have fixed clock so we're switching to use of constant values instead of something derived from core clock frequency. Among other things this will allow us to get rid of arc_{get|set}_core_freq() and switch to generic clock framework later on.
