[PATCH v2 00/26] Enable LT PHY

[Suraj Kandpal]

From Xe3p we move on to LT PHY from CX0 PHY. This series implements
all the required enable/disable sequences, DP/HDMI PLL state calculation
using tables, HDMI Algorithm to calculate PLL state and the reverse Algo
where we use the state to calculate the portclock, new Vswing tables and
programming required to get everything up and running.

[PATCH v2 02/26] drm/i915/cx0: Change register bit naming for powerdown values

[Suraj Kandpal]

Change the register bit naming for powerdown values from CX0 to
XELPDP so that it can be used with LT Phy too.

[PATCH v2 03/26] drm/i915/ltphy: Phy lane reset for LT Phy

[Suraj Kandpal]

Define function to bring phy lane out of reset for LT Phy and the
corresponding pre-requisite steps before we follow the steps for
Phy lane reset. Also create a skeleton of LT PHY PLL enable sequence
function in which we can place this function

[PATCH v2 06/26] drm/i915/ltphy: Add a wrapper for LT Phy powerdown change sequence

[Suraj Kandpal]

Add a wrapper on cx0 powerdown change sequence for LT Phy usage,
as the sequence remains unchanged when going from SNPS Phy to
LT Phy.

[PATCH v2 07/26] drm/i915/ltphy: Read PHY_VDR_0_CONFIG register

[Suraj Kandpal]

Read PHY_VDR_0_CONFIG to check if there is any change in the register and
decide based on that if P2P sequence to change the data rate of LT PHY
are required or not. This scenario only happens if the requested mode
uses 1.62Gbps with DP mode since LT PHY defaults to this mode if
any other mode is requested we need to follow the whole sequence.

[PATCH v2 10/26] drm/i915/ltphy: Update the ltpll config table value for eDP

[Suraj Kandpal]

When we get the eDP tables we reuse dp tables for some data rates.
We need to modify the 3rd config value of this table to 1 instead
of 0 since that is the only difference in the dp and edp table for
that particular data rate.

I think you mean previous versions of the algorithm here.

Since the algorithm is introduced first time in this patch, the commit 
message should reflect that.

As I understand, the function intel_lt_phy_calc_hdmi_port_clock() helps 
to derive the port clock from the LT phy register values which helps in 
readout and compare the LT phyold/new states.

Few of the things that should be mentioned in the commit message:

-Why this is needed for HDMI.

-The fact  that the function to calculate LT Phy port clock is the 
inverse of the function provided in Bspec: 74667.

This is not used.

Since this is 38400Khz, REF_CLK_KHZ would be better.

The algorithm uses + in the formulae above but as per my understanding 
the intention is to combine the non-overlapping bits.

So I agree with the above reasoning and the method to derive `d8` and 
`m2div_int` from the register values.

Since this is not very explicit, the comment can be bit improved to 
mention the formulae first and then the reasoning about the bits each 
constituent takes, something like:

         /*
          * The algorithm uses '+' to combine bitfields when 
constructing PLL_reg3 and PLL_reg57:
          * PLL_reg57 = (D7 << 24) + (postdiv << 15) + (D8 << 7) + D6_new;
          * PLL_reg3 = (D4 << 21) + (D3 << 18) + (D1 << 15) + (m2div_int 
<< 5);
          *
          * However, this is likely intended to be a bitwise OR operation,
          * as each field occupies distinct, non-overlapping bits in the 
register.
          *
          * PLL_reg57 is composed of following fields packed into a 
32-bit value:
          * - D7: max value 10 -> fits in 4 bits -> placed at bits 24-27
          * - postdiv: max value 9 -> fits in 4 bits -> placed at bits 15-18
          * - D8: derived from loop_cnt / 2, max 127 -> fits in 7 bits 
(though 8 bits are given to it) -> placed at bits 7-14
          * - D6_new: fits in lower 7 bits -> placed at bits 0-6
          * PLL_reg57 = (D7 << 24) | (postdiv << 15) | (D8 << 7) | D6_new;
          *
          * Similarly, PLL_reg3 is packed as:
          * - D4: max value 256 -> fits in 9 bits -> placed at bits 21-29
          * - D3: max value 9 -> fits in 4 bits -> placed at bits 18-21
          * - D1: max value 2 -> fits in 2 bits -> placed at bits 15-16
          * - m2div_int: max value 511 -> fits in 9 bits (10 bits 
allocated) -> placed at bits 5-14
          * PLL_reg3 = (D4 << 21) | (D3 << 18) | (D1 << 15) | (m2div_int 
<< 5);
          */

temp1 + temp0 is effectively m2div. Since  m2div = val / 2 / refclk_mhz 
and val  = d8 * clk * 10; m2div should be multiplied with a factor of 2.

Perhaps I am missing something? It would be good to document how this is 
derived.

[PATCH v2 13/26] drm/i915/ltphy: Program the P2P Transaction flow for LT Phy

[Suraj Kandpal]

Program the LT PHY P2P transaction which uses P2M cycle to get
get data fro Phy when it is ready and then go read the MAC register
from the MAC address space.

[PATCH v2 16/26] drm/i915/ltphy: Program LT Phy Non-TBT PLL disable sequence

[Suraj Kandpal]

Program in the steps for Non TBT PLL disable sequence.
The whole function can be defined in one shot since most of
prequiste functions are already coded in.

[PATCH v2 17/26] drm/i915/ltphy: Hook up LT Phy Enable & Disable sequences

[Suraj Kandpal]

Hook up the LT Phy enable and disable sequences using encoder->
enable/disable_clock and reusing the TBT enable disable sequence from
cx0 PHY since it remains the same.

I think with refclk_mhz and frequency_mhz we are going to loose 
precision. Perhaps we should use khz versions.

I think we can ditch the switch case and simply put:

ppm_value = ppm_cnt == 2 ? 2 : 1

dco_min_freq_lowcan be local, or perhaps directly use the values here.

We can have a separate function with above code that fills 
target_dco_mhz and loop_cnt.

This variable is set multiple times but is used only in below line. So 
just initialize this with 15.

I think this again can be a separate function to compute dcofine.

I understand these addresses are given in decimal but these will make 
more sense in hex.

pll_reg4_addr = pll_type ? 0x8710 : 0x8510;
pll_reg3_addr = pll_type ? 0x870C : 0x850C;

I am wondering we should put them in lt_phy_regs.h and define macros 
such that we can use:

pll_reg4_addr = PLL_REG4_ADDR(pll_type);

The change seems to be inline with the Bspec overall.

I think you can change some of the variable names like dcofine, biastrim 
to dco_fine, bias_trim etc. to be consistent with rest of the code.
