Transfer size of zero means a request to do an address-only
transfer. Since the HW support this, we probably shouldn't be just
ignoring such requests. While at it allow DP_AUX_I2C_MOT flag to pass

Implementation of tc_poll_timeout() is almost a 100% copy-and-paste of
the code for regmap_read_poll_timeout(). Replace copied code with a
call to the original. While at it change tc_poll_timeout to accept
"struct tc_data *" instead of "struct regmap *" for brevity. No
functional change intended.
Currently, all dma-bufs share the same anonymous inode. While we can count
how many dma-buf fds or mappings a process has, we can't get the size of
the backing buffers or tell if two entries point to the same dma-buf. And

tc_wait_pll_lock() is always called as a follow-up for updating
PLLUPDATE and PLLEN bit of a given PLL control register. To simplify
things, merge the two operation into a single helper function
tc_pllupdate_pllen() and convert the rest of the code to use it. No

This commit converts "unsigned int" and "int" in I/O wrappers
to "u8". It improves readability since it's consistent with
the prototypes of readb() and writeb(). More importantly, it
reduces readers' confusion, since the upcoming 2D acceleration
code will use a different wordsize.

Simplify AUX data read by removing index arithmetic and shifting with

1. Fetch data from up to 4 32-bit registers from the chip

3. Copy read data into user provided array.

Don't assume that requested data transfer size is the same as amount
of data that was transferred. Change the code to get that information
from DP0_AUXSTATUS instead.
Since the check for AUX_BUSY in tc_aux_get_status() is pointless (it
will always called after tc_aux_wait_busy()) and there's only

Move common code converting clock rate to an appropriate constant and
configuring SYS_PLLPARAM register into a separate routine and convert
the rest of the code to use it. No functional change intended.

This patch works on my odroid xu4 too, on 5.0.3 kernel.

We don't need 8 byte array, DP_LINK_STATUS_SIZE (6) should be
enough. This also gets rid of a magic number as a bonus.

If the scaling loop in drm_fb_helper_single_fb_probe() only finds
supported depths greater than what it's looking for, it will set

This commits add information about 32-bit color, 2D acceleration,
as well as adding additional, general information about the hardware
and many existing problems of the sm712fb driver.

Simplify AUX data write by dropping index arithmetic and shifting and
replacing it with a call to a helper function that does three things:
1. Copies user-provided data into a write buffer
2. Optionally fixes the endianness of the write buffer (not needed
on LE hosts)
3. Transfe
A very unfortunate aspect of tc_write()/tc_read() macro helpers is
that they capture quite a bit of context around them and thus require
the caller to have magic variables 'ret' and 'tc' as well as label
'err'. That makes a number of code paths rather counterintuitive and
somewhat clunky, for examp
Everyone:
This series contains various improvements (at least in my mind) and
fixes that I made to tc358767 while working with the code of the
driver. Hopefuly each patch is self explanatory.
Feedback is welcome!

tc_get_display_props() never reads more than a byte via AUX, so
there's no need to reserve 8 for that purpose. No function change
intended.

This commit adds I/O macros and functions related to 2D opeartions.
A hunk of hardware register definitions are taken verbatim from
OpenBSD.
In addition, a utility function pad_to_dword() is added to help
padding data for the 2D engine. It accepts 3, 2, or 1 byte(s) of
data, and pads it to a 32-b
