[WHY] SCR for DP 2.0 spec says that multiple LTTPRs must not be accessed in a single AUX transaction. There may be other places in future where breaking up AUX accesses is necessary. [HOW] Partition the entire DPCD address space into blocks. When an incoming AUX request spans multiple blocks, break up the request into multiple requests. Signed-off-by:

[WHY] DP 2.0 SCR specifies that "A DPTX shall distinguish I2C_DEFER|AUX_ACK from AUX_DEFER. AUX retries due to I2C_DEFER are not counted as part of minimum 7 retires (sic) upon AUX_DEFER’s" Signed-off-by:

[WHY] DP 2.0 SCR specifies that TX devices must retry at least 7 times when receiving an AUX DEFER reply from RX. In addition, the specification states that the TX shall not retry indefinitely, and gives a suggestive timeout interval of 50ms. [HOW] Keep retrying until both 7 or more retries have been made, and the 50ms interval has passed. Signed-off-by:

[WHY] Some DPCD addresses, notably LTTPR Capability registers, are expected to be read all together in a single DPCD transaction. Rather than force callers to read registers they don't need, we want to quietly extend the addresses read, and only return back the values the caller asked for. This does not affect DPCD writes. [HOW] Create an additional layer above AUX to perform 'checked' DPCD transactions. Iterate through an array of DPCD address ranges that are marked as being contiguous. If a requested read falls within one of those ranges, extend the read to include the entire range. After DPCD has been queried, copy the requested bytes into the caller's data buffer, and deallocate all resources used. Signed-off-by:

[WHY] DP specifies that an LTTPR device is only present if PHY_REPEATER_CNT is 0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, or 0x01. All other values should be considered no LTTPRs present. [HOW] Function dp_convert_to_count already does this check. Use it to determine if PHY_REPEATER_CNT is a valid LTTPR count. Signed-off-by:

[WHY] SCR for DP2.0 requires that LT be performed with PHY_REPEATER_MODE programmed to 0x55 (Transparent) whenever PHY_REPEATER_CNT is any value other than 0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, or 0x01. [HOW] Write Non-Transparent (0xAA) to PHY_REPEATER_MODE when LTTPRs detected and Non-Transparent is requested. Write Transparent in all other cases. Signed-off-by:

[WHY] SCR for DP 2.0 Spec states that a DPTX shall put LTTPRs into Transparent mode after reading LTTPR Capability registers on HPD. The wording of the SCR is somewhat ambiguous as to whether Transparent mode must be set explicity, or is implicitly set on LTTPR capability read. Explicitly setting Transparent mode after LTTPR capability read should cover all cases. Signed-off-by:
