From 15ac408ee5a509053a765b816e9179515329369f Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Fri, 28 Aug 2009 10:51:31 -0700 Subject: OMAP: UART: drop OMAP_TAG_UART, enable all UARTs, auto-disabled on idle OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

This needs to happen earlier, at some point before omap2_init_common_hw() is called. This is because a future patch will use the bootloader serial console port information to enable the UART clocks earlier, immediately after omap2_clk_init(). This is in turn necessary since otherwise clock tree usecounts on clocks like dpll4_m2x2_ck will be bogus, which can cause the currently-active console UART clock to be disabled during boot.
