From ff3bbc5c637ab0843b3a9df717b6cca4e8243f0c Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Tue, 11 Nov 2014 11:30:09 -0800 Subject: [PATCH] mfd/axp20x: avoid irq numbering collision IRQ numbers in axp20x devices are defined with high-order bit first in each IRQ enable/status registers. On Intel platforms it is more common to number IRQs with least significant bit first. Therefore, sharing IRQ# between the two is very difficult. Since AXP288 is a customized PMIC for Intel platform and the amount of shared IRQs are very small, we use separate IRQ numbering. This also fixes collision and a duplicate in WBTO interrupt. e.g. For the 16 interrupts controlled in IRQ enabled registers 1 & 2, on axp20x for ARM, the PMIC local IRQ numbers and register bits are mapped as: IRQ#: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 --------------------------------------------------------- ARM: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 Intel: 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 Signed-off-by: Todd Brandt Signed-off-by: Jacob Pan Acked-by: Jonathan Cameron Signed-off-by: Lee Jones --- drivers/mfd/axp20x.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/drivers/mfd/axp20x.c b/drivers/mfd/axp20x.c index b2fb7f492c86..9c4714e13c3c 100644 --- a/drivers/mfd/axp20x.c +++ b/drivers/mfd/axp20x.c @@ -183,21 +183,21 @@ static const struct regmap_irq axp20x_regmap_irqs[] = { /* some IRQs are compatible with axp20x models */ static const struct regmap_irq axp288_regmap_irqs[] = { - INIT_REGMAP_IRQ(AXP20X, VBUS_REMOVAL, 0, 2), - INIT_REGMAP_IRQ(AXP20X, VBUS_PLUGIN, 0, 3), - INIT_REGMAP_IRQ(AXP20X, VBUS_OVER_V, 0, 4), + INIT_REGMAP_IRQ(AXP288, VBUS_FALL, 0, 2), + INIT_REGMAP_IRQ(AXP288, VBUS_RISE, 0, 3), + INIT_REGMAP_IRQ(AXP288, OV, 0, 4), - INIT_REGMAP_IRQ(AXP20X, CHARG_DONE, 1, 2), - INIT_REGMAP_IRQ(AXP20X, CHARG, 1, 3), + INIT_REGMAP_IRQ(AXP288, DONE, 1, 2), + INIT_REGMAP_IRQ(AXP288, CHARGING, 1, 3), INIT_REGMAP_IRQ(AXP288, SAFE_QUIT, 1, 4), INIT_REGMAP_IRQ(AXP288, SAFE_ENTER, 1, 5), - INIT_REGMAP_IRQ(AXP20X, BATT_REMOVAL, 1, 6), - INIT_REGMAP_IRQ(AXP20X, BATT_PLUGIN, 1, 7), + INIT_REGMAP_IRQ(AXP288, ABSENT, 1, 6), + INIT_REGMAP_IRQ(AXP288, APPEND, 1, 7), INIT_REGMAP_IRQ(AXP288, QWBTU, 2, 0), INIT_REGMAP_IRQ(AXP288, WBTU, 2, 1), INIT_REGMAP_IRQ(AXP288, QWBTO, 2, 2), - INIT_REGMAP_IRQ(AXP288, WBTU, 2, 3), + INIT_REGMAP_IRQ(AXP288, WBTO, 2, 3), INIT_REGMAP_IRQ(AXP288, QCBTU, 2, 4), INIT_REGMAP_IRQ(AXP288, CBTU, 2, 5), INIT_REGMAP_IRQ(AXP288, QCBTO, 2, 6), @@ -215,7 +215,7 @@ static const struct regmap_irq axp288_regmap_irqs[] = { INIT_REGMAP_IRQ(AXP288, POKS, 4, 4), INIT_REGMAP_IRQ(AXP288, POKN, 4, 5), INIT_REGMAP_IRQ(AXP288, POKP, 4, 6), - INIT_REGMAP_IRQ(AXP20X, TIMER, 4, 7), + INIT_REGMAP_IRQ(AXP288, TIMER, 4, 7), INIT_REGMAP_IRQ(AXP288, MV_CHNG, 5, 0), INIT_REGMAP_IRQ(AXP288, BC_USB_CHNG, 5, 1), -- 2.39.5
