After searching around for a similar issue, I came across an earlier fix
that never got merged upstream in the Android tree for glass-omap-xrr02.
There is patch "MFD: twl6040-codec: Implement PDMCLK cold temp errata"
by Misael Lopez Cruz <misael.lopez@ti.com>.
Based on my observations, this fix is also needed when cold booting
devices, and not just for deeper idle modes. Since we now have a clock
driver for pdmclk, let's fix the issue in twl6040_pdmclk_prepare().

GSO packets with vnet_hdr must conform to a small set of gso_types.
The below commit uses flow dissection to drop packets that do not.
But it has false positives when the skb is not fully initialized.
Dissection needs skb->protocol and skb->network_header.
Infer skb->protocol from gso_type as the two must agree.
SKB_GSO_UDP can use both ipv4 and ipv6, so try both.

The current implementation of gpio-gate-clk enables/disables the clock
using the GPIO in the ->enable() and ->disable() clock callbacks. This
requires the GPIO to be configurable in atomic contexts. While it is
the case for most memory-mapped GPIO controllers, it is not the case
for GPIO expanders on I2C or SPI.
This commit extends the gpio-gate-clk to check whether the GPIO calls
require sleeping or not. If sleeping is not required, the current
implementation based on ->enable()/->disable() is kept. However, if
sleeping is needed, we instead implement the logic in the ->prepare()
and ->unprepare() hooks. Thanks to this, a gate clock connected to a
GPIO on a GPIO expander can be controlled with the existing driver.

The clk-rpmh driver only supports on and off RPMh clock resources. Let's
extend the driver by adding support for clocks that are managed by a
different type of RPMh resource known as Bus Clock Manager(BCM). The BCM
is a configurable shared resource aggregator that scales performance
based on a set of frequency points. The Qualcomm IP Accelerator (IPA)
clock is an example of a resource that is managed by the BCM and this a
requirement from the IPA driver in order to scale its core clock.

These are in fact two clocks, they shouldn't be exposed as one. One is
required for accessing LCD controller registers (peripheral clock), while
other (AXI clock) can be optionally used as a pixel clock source for the
panel.
LCDC can alternatively use different clocks than the Display 1 AXI clock
for generating the pixel clock: the second AXI clock (fixed in this
commit too), the HDMI PLL, or the AXI bus clock.
They should really be controlled independently.

This patch fixes a subtle PACKET_ORIGDEV regression which was a side
effect of fixes introduced by:
6a9e461f6f bonding: pass link-local packets to bonding master also.
... to:
b89f04c61e bonding: deliver link-local packets with skb->dev set to link that packets arrived on
While 6a9e461f6f restored pre-b89f04c61efe presence of link-local
packets on bonding masters (which is required e.g. by linux bridges
participating in spanning tree or needed for lab-like setups created
with group_fwd_mask) it also caused the originating device
information to be lost due to cloning.
Maciej Żenczykowski proposed another solution that doesn't require
packet cloning and retains original device information - instead of
returning RX_HANDLER_PASS for all link-local packets it's now limited
only to packets from inactive slaves.
At the same time, packets passed to bonding masters retain correct
information about the originating device and PACKET_ORIGDEV can be used
to determine it.
This elegantly solves all issues so far:
- link-local packets that were removed from bonding masters
- LLDP daemons being forced to explicitly bind to slave interfaces
- PACKET_ORIGDEV having no effect on bond interfaces

clear any combination of multicast entries (static or not static) and
multicast vifs (static or not static).
Calling the new socket option MRT_FLUSH with the flags MRT_FLUSH_MFC and
