Subject: 85xx,86xx: Determine I2C clock frequencies and store in global_data
X-Git-Tag: v2025.01-rc5-pxa1908~22534^2^2~3
X-Git-Url: http://git.dujemihanovic.xyz/img/%7B%7B%20%24image.RelPermalink%20%7D%7D?a=commitdiff_plain;h=e56b4b494cd92def577969f9678395aa22d34c9f;p=u-boot.git

85xx,86xx: Determine I2C clock frequencies and store in global_data

Update global_data to define i2c1_clk and i2c2_clk to 85xx and 86xx.

Update the get_clocks() function in 85xx and 86xx to determine the I2C
clock frequency and store it in gd->i2c1_clk and gd->i2c2_clk.
