5twl_irq_init() clears PWR interrupt status bits, then masks the interrupts
6off, then clears the PWR interrupt status bits again. The first clear

1TWL4030: clear TWL GPIO interrupt status registers
2
3From: Paul Walmsley <paul@pwsan.com>
4
5twl_init_irq() does not clear the TWL GPIO ISR registers, but the PIH
6ISR thinks that it has. This causes any previously-latched GPIO interrupts
7to be stuck on until twl4030-gpio.c initializes, often drowning the console in
8
9 TWL4030 module irq 368 is disabled but can't be masked!

1TWL4030: use correct register addresses for BCI IMR registers

3From: Paul Walmsley <paul@pwsan.com>
4
5The existing code to mask and clear BCI interrupts in twl_init_irq() is
6wrong. It uses the wrong register offsets, it does not mask all of the
7BCI IMR registers, and it does not clear all of the BCI ISR registers.

1TWL4030: use *_SIH_CTRL.COR bit to determine whether to read or write ISR to clear
2
3From: Paul Walmsley <paul@pwsan.com>
4
5TWL4030 interrupt status register bits can be cleared in one of two ways:
6either by reading from the register, or by writing a 1 to the
7appropriate bit(s) in the register. This behavior can be altered at any
8time by the <twlmodule>_SIH_CTRL.COR register bit ("clear-on-read").
9
10The TWL4030 TRM is deeply confused as to whether COR=1 means that the
11registers are cleared on reads, or cleared on writes. Peter De
12Schrijver <peter.de-schrijver> confirms that COR=1 means that the registers
13are cleared on read.
14
15So, for each TWL4030 SIH, check the value of the *_SIH_CTRL.COR bit, and if
16it is 1, use reads to clear the ISRs; if it is 0, use writes.
17
18Also, use WARN_ON() to warn if the read/write failed, and don't skip
19the rest of the initialization on failure either.
20
21Thanks to Peter for his help with this patch.

1TWL4030: change init-time IMR mask code to WARN if error
2
3From: Paul Walmsley <paul@pwsan.com>
4
5twl_init_irq() prints error messages and returns if any interrupt mask
6register writes fail. Change this to generate a warning traceback and
7to continue execution rather than skipping TWL init. (These mask
8writes should not fail at all unless either the I2C bus or the TWL4030
9is somehow wedged.)

1TWL4030: move TWL module register defs into separate include files
2
3From: Paul Walmsley <paul@pwsan.com>
4
5twl_init_irq() uses "magic numbers" to access TWL module IMR and ISR
6registers. Symbolic constants are definitely preferred.
7
8Rather than duplicating already existing symbolic constants in
9twl4030-gpio.c and twl4030-pwrirq.c, move the existing constants out
10into include files. This patch should not change kernel behavior.

1TWL4030: use symbolic ISR/IMR register names during twl_init_irq()
2
3From: Paul Walmsley <paul@pwsan.com>
4
5twl_init_irq() uses a bunch of magic numbers as register indices; this
6has already led to several errors, fixed earlier in this patch series.
7Now use descriptive macros instead of magic numbers. This patch should
8not change kernel behavior.

1TWL4030: convert early interrupt mask/clear funcs to use array
2
3From: Paul Walmsley <paul@pwsan.com>
4
5Mask/clear TWL module IMRs/ISRs by iterating through arrays rather than
6using a block of cut-and-pasted commands. Removes 1056 bytes of bloat.

49omap_i2c_idle() sets an internal flag, "dev->idle", instructing its
50ISR to decline interrupts. It sets this flag before it actually masks
51the interrupts on the I2C controller. This is problematic, since an
52I2C interrupt could arrive after dev->idle is set, but before the
53interrupt source is masked. When this happens, Linux disables the I2C
54controller's IRQ, causing all future transactions on the bus to fail.
55
56Symptoms, happening on about 7% of boots:
57
58 irq 56: nobody cared (try booting with the "irqpoll" option)
59 <warning traceback here>
60 Disabling IRQ #56
61 i2c_omap i2c_omap.1: controller timed out
62
63In omap_i2c_idle(), this patch sets dev->idle only after the interrupt
64mask write to the I2C controller has left the ARM write buffer.
65That's probably the major offender. For additional prophylaxis, in
66omap_i2c_unidle(), the patch clears the dev->idle flag before
67interrupts are enabled, rather than afterwards.
68
69The patch has survived twenty-two reboots on the 3430SDP here without
70wedging I2C1. Not absolutely dispositive, but promising!

8Filling the set_rate and round_rate fields of dpll4_m4_ck makes
9this clock programmable through clk_set_rate(). This is needed
10to give omapfb control over the dss1_alwon_fck rate.

6ARM: OMAP: Set DSS1_ALWON_FCLK to a multiple of the pixel clock
7
8This sets the DSS1_ALWON_FCLK clock as close as possible to a
9multiple of the requested pixel clock, while keeping it below
10the 173MHz limit.
11
12Due to of the structure of the clock tree, dss1_alwon_fck cannot
13be set directly, and we must use dpll4_m4_ck instead.
