From 70e8be0a4e21f71e654bea2e5ec4789e976a796b Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 25 Jul 2007 10:50:42 +0900 Subject: sh: intc - add support for SH7705 This patch converts the cpu specific interrupt setup code for sh7705 from ipr to intc. While at it new vectors are added to match the information provided by the datasheet. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also adds sh7705 specific platform data for the rtc driver.

All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.
