[PATCH v4 1/9] mfd: intel_soc_pmic_bxtwc: fix TMU interrupt index

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

TMU interrupts are registered as a separate interrupt chip, and
hence it should start its interrupt index(BXTWC_TMU_IRQ) number
from 0. But currently, BXTWC_TMU_IRQ is defined as part of enum
bxtwc_irqs_level2 and its index value is 11. Since this index
value is used when calculating .num_irqs of regmap_irq_chip_tmu,
it incorrectly reports number of irqs as 12 instead of actual
value of 1.

This patch fixes this issue by creating new enum of tmu irqs and
resetting its starting index to 0.

[PATCH v4 2/9] mfd: intel_soc_pmic_bxtwc: remove thermal second level irqs

[sathyanarayanan.kuppuswamy-VuQAYsv1563Yd54FQh9/CA]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>

Since all second level thermal irqs are consumed by the same
device(bxt_wcove_thermal), there is no need to expose them as separate
interrupts. We can just export only the first level irqs for thermal and
let the device(bxt_wcove_thermal) driver handle the second level irqs
based on thermal interrupt status register. Also, just using only the
first level irq will eliminate the bug involved in requesting only the
second level irq and not explicitly enable the first level irq. For
more info on this issue please read the details at,

[PATCH v4 3/9] thermal: intel_bxt_pmic_thermal: use first level PMIC thermal irq

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

PMIC mfd driver only exports first level irq for thermal device.
But currently we are reading the irqs from the second level irq
chip, So this patch fixes this issue by adding support to use
first level PMIC thermal irq.

[PATCH v4 3/9] thermal: intel_bxt_pmic_thermal: use first level PMIC thermal irq

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

PMIC mfd driver only exports first level irq for thermal device.
But currently we are reading the irqs from the second level irq
chip, So this patch fixes this issue by adding support to use
first level PMIC thermal irq.

[PATCH v4 7/9] mfd: intel_soc_pmic_bxtwc: use chained irqs for second level irq chips

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Whishkey cove PMIC has support to mask/unmask interrupts at two levels.
At first level we can mask/unmask interrupt domains like TMU, GPIO, ADC,
CHGR, BCU THERMAL and PWRBTN and at second level, it provides facility
to mask/unmask individual interrupts belong each of this domain. For
example, in case of TMU, at first level we have TMU interrupt domain,
and at second level we have two interrupts, wake alarm, system alarm that
belong to the TMU interrupt domain.

Currently, in this driver all first level irqs are registered as part of
irq chip(bxtwc_regmap_irq_chip). By default, after you register the irq
chip from your driver, all irqs in that chip will masked and can only be
enabled if that irq is requested using request_irq call. This is the
default Linux irq behavior model. And whenever a dependent device that
belongs to PMIC requests only the second level irq and not explicitly
unmask the first level irq, then in essence the second level irq will
still be disabled. For example, if TMU device driver request wake_alarm
irq and not explicitly unmask TMU level 1 irq then according to the default
Linux irq model,  wake_alarm irq will still be disabled. So the proper
solution to fix this issue is to use the chained irq chip concept. We
should chain all the second level chip irqs to the corresponding first
level irq. To do this, we need to create separate irq chips for every
group of second level irqs.

In case of TMU, when adding second level irq chip, instead of using pmic
irq we should use the corresponding first level irq. So the following
code will change from

ret = regmap_add_irq_chip(pmic->regmap, pmic->irq, ...)

to,

virq = regmap_irq_get_virq(&pmic->irq_chip_data, BXTWC_TMU_LVL1_IRQ);

ret = regmap_add_irq_chip(pmic->regmap, virq, ...)

[PATCH v4 7/9] mfd: intel_soc_pmic_bxtwc: use chained irqs for second level irq chips

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Whishkey cove PMIC has support to mask/unmask interrupts at two levels.
At first level we can mask/unmask interrupt domains like TMU, GPIO, ADC,
CHGR, BCU THERMAL and PWRBTN and at second level, it provides facility
to mask/unmask individual interrupts belong each of this domain. For
example, in case of TMU, at first level we have TMU interrupt domain,
and at second level we have two interrupts, wake alarm, system alarm that
belong to the TMU interrupt domain.

Currently, in this driver all first level irqs are registered as part of
irq chip(bxtwc_regmap_irq_chip). By default, after you register the irq
chip from your driver, all irqs in that chip will masked and can only be
enabled if that irq is requested using request_irq call. This is the
default Linux irq behavior model. And whenever a dependent device that
belongs to PMIC requests only the second level irq and not explicitly
unmask the first level irq, then in essence the second level irq will
still be disabled. For example, if TMU device driver request wake_alarm
irq and not explicitly unmask TMU level 1 irq then according to the default
Linux irq model,  wake_alarm irq will still be disabled. So the proper
solution to fix this issue is to use the chained irq chip concept. We
should chain all the second level chip irqs to the corresponding first
level irq. To do this, we need to create separate irq chips for every
group of second level irqs.

In case of TMU, when adding second level irq chip, instead of using pmic
irq we should use the corresponding first level irq. So the following
code will change from

ret = regmap_add_irq_chip(pmic->regmap, pmic->irq, ...)

to,

virq = regmap_irq_get_virq(&pmic->irq_chip_data, BXTWC_TMU_LVL1_IRQ);

ret = regmap_add_irq_chip(pmic->regmap, virq, ...)

[PATCH v4 8/9] platform: x86: intel_bxtwc_tmu: remove first level irq unmask

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Currently in WCOVE PMIC mfd driver, all second level irq chips
are chained to the respective first level irqs. So there is no
need for explicitly unmasking the first level irq in this
driver. This patches removes this level 1 irq unmask support.

[PATCH v4 9/9] usb: typec: typec_wcove: Use charger irq chip to get usbc virq

[sathyanarayanan.kuppuswamy]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Currently, in Whiskey cove PMIC driver, USBC IRQ is moved under charger
level2 irq chip. So use irq_chip_data_chgr to get the USBC virtual IRQ
number.
