Shouldn't be this squashed to patch 2?

There is no compilation dependency between patch 2 and 3. But they are
functionally dependent.

Should we squash functionally dependent patches too ?

Let's assume we applied patches 1 and 2, does it mean the regression
to the existing behaviour?

(For example, device worked improperly in some cases -> stopped
working completely)

Yes, Just applying patch 1 & 2 and not apply patch 3 will create
regression in thermal driver.

Since there is no compilation dependency between patch 2 & 3 and they
are from two different domains, I submitted them separately to make it
easier for review.

And this is exactly bisectability (level 2 :-) ) issue.
Basically you confirmed you need to squash them like I said.

Subject: [PATCH v6 6/6] platform/x86: intel_bxtwc_tmu: Remove first level IRQ unmask

From: Kuppuswamy Sathyanarayanan <[email protected]>

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.

Subject: [PATCH v6 5/6] mfd: intel_soc_pmic_bxtwc: Use chained IRQs for second level IRQ chips

From: Kuppuswamy Sathyanarayanan <[email protected]>

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, ...)

In case of Whiskey Cove Type-C driver, Since USBC IRQ is moved under
charger level2 IRQ chip. We should use charger IRQ chip(irq_chip_data_chgr)
to get the USBC virtual IRQ number.

mfd: intel_soc_pmic_bxtwc: use chained irqs for second level irq chips

Changes since v5:
* Changed irq->IRQ, pmic->PMIC in all commit messages.
* Squashed following two thermal driver related commits.
mfd: intel_soc_pmic_bxtwc: Remove thermal second level irqs

Subject: [PATCH v6 2/6] mfd: intel_soc_pmic_bxtwc: Remove thermal second level IRQs

From: Kuppuswamy Sathyanarayanan <[email protected]>

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,

https://lkml.org/lkml/2017/2/27/148

This patch also makes relevant change in bxt_wcove_thermal driver to use
only first level PMIC thermal IRQ.

Subject: [PATCH v6 3/6] mfd: intel_soc_pmic_bxtwc: Remove second level IRQ for gpio device

From: Kuppuswamy Sathyanarayanan <[email protected]>

Currently all PMIC GPIO domain IRQs are consumed by the same
device(bxt_wcove_gpio), so there is no need to export them as
separate interrupts. We can just export only the first level
GPIO IRQ(BXTWC_GPIO_LVL1_IRQ) as an IRQ resource and let the
GPIO device driver(bxt_wcove_gpio) handle the GPIO sub domain
IRQs based on status value of GPIO level2 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,

https://lkml.org/lkml/2017/2/27/148

This patch also makes relevant change in Whiskey cove GPIO driver to
use only first level PMIC GPIO IRQ.

Subject: [PATCH v6 1/6] mfd: intel_soc_pmic_bxtwc: Fix TMU interrupt index

From: Kuppuswamy Sathyanarayanan <[email protected]>

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.
