[PATCH AUTOSEL 6.6 06/52] net: stmmac: dwmac-starfive: Add support for JH7100 SoC

[Sasha Levin]

From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>

[ Upstream commit 8d4597b871210429bda0f5c3a8816b7d9b6daf7e ]

Add a missing quirk to enable support for the StarFive JH7100 SoC.

Additionally, for greater flexibility in operation, allow using the
rgmii-rxid and rgmii-txid phy modes.

[PATCH AUTOSEL 6.6 14/52] cpuidle: Avoid potential overflow in integer multiplication

[Sasha Levin]

From: C Cheng <C.Cheng@mediatek.com>

[ Upstream commit 88390dd788db485912ee7f9a8d3d56fc5265d52f ]

In detail:

In C language, when you perform a multiplication operation, if
both operands are of int type, the multiplication operation is
performed on the int type, and then the result is converted to
the target type. This means that if the product of int type
multiplication exceeds the range that int type can represent,
an overflow will occur even if you store the result in a
variable of int64_t type.

For a multiplication of two int values, it is better to use
mul_u32_u32() rather than s->exit_latency_ns = s->exit_latency *
NSEC_PER_USEC to avoid potential overflow happenning.

[PATCH AUTOSEL 6.6 21/52] pmdomain: imx8mp-blk-ctrl: imx8mp_blk: Add fdcc clock to hdmimix domain

From: Adam Ford <aford173@gmail.com>

[ Upstream commit 697624ee8ad557ab5417f985d2c804241a7ad30d ]

According to i.MX8MP RM and HDMI ADD, the fdcc clock is part of
hdmi rx verification IP that should not enable for HDMI TX.
But actually if the clock is disabled before HDMI/LCDIF probe,
LCDIF will not get pixel clock from HDMI PHY and print the error
logs:

[CRTC:39:crtc-2] vblank wait timed out
WARNING: CPU: 2 PID: 9 at drivers/gpu/drm/drm_atomic_helper.c:1634 drm_atomic_helper_wait_for_vblanks.part.0+0x23c/0x260

Add fdcc clock to LCDIF and HDMI TX power domains to fix the issue.

[PATCH AUTOSEL 6.6 31/52] wifi: mt76: mt7996: add locking for accessing mapped registers

[Sasha Levin]

From: Shayne Chen <shayne.chen@mediatek.com>

[ Upstream commit 3687854d3e7e7fd760d939dd9e5a3520d5ab60fe ]

A race condition was observed when accessing mapped registers, so add
locking to protect against concurrent access.

[PATCH AUTOSEL 6.6 51/52] Bluetooth: btmtk: Add MODULE_FIRMWARE() for MT7922

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 3e465a07cdf444140f16bc57025c23fcafdde997 ]

Since dracut refers to the module info for defining the required
firmware files and btmtk driver doesn't provide the firmware info for
MT7922, the generate initrd misses the firmware, resulting in the
broken Bluetooth.

This patch simply adds the MODULE_FIRMWARE() for the missing entry
for covering that.
