From mboxrd@z Thu Jan 1 00:00:00 1970 From: augulis.darius@gmail.com (Darius Augulis) Date: Sun, 07 Nov 2010 21:58:27 +0200 Subject: [PATCH] ARM: S3C64XX: fix uart clock setup for mini6410/real6410 Message-ID: <20101107195738.9835.47554.stgit@localhost6.localdomain6> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Don't rewrite clock config in UCON preconfigured by bootloader. No need to set 10th bit in UCON because [11:10] 2'b00 means source clock is PCLK too. If set, console does not work if bootloader has preconfigured [11:10] with 2'b00. If not set, console works with any bootloader config value (2'bxx). More information about clock setup in UCON is available in "S3C6410X RISC Microprocessor User's Manual, Revision 1.20" p. 31-13 (Chapter 31.6.2 UART CONTROL REGISTER).
