From 354e57f3a0a26120af3bcd6c92c355ad00a057c1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 7 Nov 2013 10:25:55 +0100 Subject: [PATCH 01/14] ARM/serial: at91: switch atmel serial to use gpiolib MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This passes the errata fix using a GPIO to control the RTS pin on one of the AT91 chips to use gpiolib instead of the AT91-specific interfaces. Also remove the reliance on compile-time #defines and the cpu_* check and rely on the platform passing down the proper GPIO pin through platform data. This is a prerequisite for getting rid of the local GPIO implementation in the AT91 platform and move toward multiplatform. The patch also adds device tree support for getting the RTS GPIO pin from the device tree on DT boot paths.

Before this commit the following was used to determine the latch value used: #define IXP4XX_TIMER_FREQ 66666000 #define CLOCK_TICK_RATE \ (((IXP4XX_TIMER_FREQ / HZ & ~IXP4XX_OST_RELOAD_MASK) + 1) * HZ) #define LATCH ((CLOCK_TICK_RATE + HZ/2) / HZ) The complicated calculation was done "b/c the timer register ignores the bottom 2 bits of the LATCH value." With HZ=100 CLOCK_TICK_RATE used to calculate to 66666100 and so LATCH to 666661. In ixp4xx_set_mode the term LATCH & ~IXP4XX_OST_RELOAD_MASK was used to write to the relevant register (with IXP4XX_OST_RELOAD_MASK being 3) and so effectively 666660 was used. In commit f0402f9b4711 I translated that to: #define IXP4XX_TIMER_FREQ 66666000 #define IXP4XX_LATCH DIV_ROUND_CLOSEST(IXP4XX_TIMER_FREQ, HZ) which results in the same register writes, but still doesn't bear in mind that the two least significant bits cannot be specified (which is relevant only when HZ or IXP4XX_TIMER_FREQ are changed). Instead of reverting back to the old approach use a more obvious and also more correct way to calculate LATCH. (Regarding the more correct claim: With IXP4XX_TIMER_FREQ == 66665999, the old code resulted in LATCH = 666657 corresponding to a cycle time of 0.009999940149400597 seconds (error: -6.0e-8 s) while the new approach results in LATCH = 666660 and so a cycle time of 0.010000000150001503 seconds (error: 1.5e-10 s).)
