+
+TWL4030 interrupt status register bits can be cleared in one of two ways:
+either by reading from the register, or by writing a 1 to the
+appropriate bit(s) in the register. This behavior can be altered at any
+time by the <twlmodule>_SIH_CTRL.COR register bit ("clear-on-read").
+
+twl4030-core.c does not touch these *_SIH_CTRL registers during boot,
+and the TWL4030 TRM is deeply confused as to whether COR=1 means that
+the registers are cleared on reads, or cleared on writes.
+
+So, take the cautious way out and both read from and write to the TWL4030
+module ISRs to clear them at startup. Also, use WARN_ON() to warn if the
+read/write failed, and don't skip the rest of the initialization on failure
+either.

+twl_init_irq() prints error messages and returns if any interrupt mask

+to continue execution rather than skipping TWL init. (These mask
+writes should not fail at all unless either the I2C bus or the TWL4030

+
+twl_init_irq() accesses TWL module IMR and ISR registers. Currently, it
+uses "magic numbers" for these register indices, but symbolic constants
+are definitely preferred. Rather than duplicating already existing
+symbolic constants in twl4030-gpio.c and twl4030-pwrirq.c, move the
+existing constants out into include files. This patch should not change
+kernel behavior.

+
+twl_init_irq() uses a bunch of magic numbers as register indices; this
+has already led to several errors, fixed earlier in this patch series.
+Now use descriptive macros instead of magic numbers. This patch should
+not change kernel behavior.
