It's unnecessary to cleanup the i2c adapter and the ddc pointer in
the bailout path of __dw_hdmi_probe(), since the adapter is not

SET_NOIRQ_SY
Patchset Summary:
Enhance a PCIe host controller driver. Because of its unusual design
we are foced to change dev->dma_pfn_offset into a more general role
allowing multiple offsets.
v5:
Commit "device core: Introduce multiple dma pfn offsets"
-- in of/address.c: "map_size = 0" => "*map_
The new field in struct device 'dma_pfn_offset_map' is used to facilitate
the use of single or multiple pfn offsets between cpu addrs and dma addrs.
It subsumes the role of dev->dma_pfn_offset -- a uniform offset.
The function of_dma_get_range() has been modified to take two additional
arguments:

Function get_insert_time can return error values that are cast
to a u64. The checks of insert_time1 and insert_time2 check for
the errors but because they are u64 variables the check for less
than zero can never be true. Fix this by casting the value to s64

mxsfb_regs.h defines macros related to register bits. Some of them are
not used and don't clearly map to any particular register, so their
purpose isn't known. Remove them.

Using BIT() is preferred over manual shifts as it's more readable,
handles the 1 << 31 case properly, and avoids other mistakes as shown by
the DEBUG0_HSYNC and DEBUG0_VSYNC bits (that are currently unused). Use
it.

Hello,
This patch series adds i.MX7 support to the mxsfb driver. The eLCDIF
instance found in the i.MX7 is backward-compatible with the already
supported LCDC v4, but has extended features amongst which the most
notable one is a second plane.
The first 10 patches (01/22 to 10/22) contain miscella
The LCDC_CTRL register is located at address 0x. Some of the

Changes since
The driver attempts agressive power management by enabling and disabling
the AXI clock around register accesses. This results in attempts to
enable and disable the clock in the IRQ handler, which is a no-go as
preparing or unpreparing the clock may sleep.
On the other hand, the driver enables the
Enable vblank handling when the CRTC is turned on and disable it when it
