Subject: [PATCH v3 3/7] clk: rockchip: rk3399: fix incorrect GATE bits for {c, g}pll_aclk_perihp_src
Date: Tue, 2 Aug 2016 15:19:57 +0800 [thread overview]
Message-ID: <1470122401-31934-4-git-send-email-zhengxing@rock-chips.com> (raw)
In-Reply-To: <1470122401-31934-1-git-send-email-zhengxing@rock-chips.com>
Sorry to refer incorrect clock diagram, we double check it that the bits
configuration of the Xpll_aclk_perihp_src need to be fixed:
bit 1 - shows aclk_perihp_cpll_src_en
bit 0 - shows aclk_perihp_gpll_src_en
Through the testing that plug/unplug the USB ethernet cable on the RK3399 kevin board.
1. the hclk_host0 and hclk_host1 are endpoint clocks:
cpll --> G5[1] --> aclk_perihp_cpll_src --\ |--> hclk_host0
| --> ... ---> |
gpll --> G5[0] --> aclk_perihp_gpll_src --/ |--> hclk_host1
2. there is no clock below the cpll_aclk_perihp_src,
and the hclk_hostX are below the gpll_aclk_perihp_src:
pll_cpll 1 1 800000000 0 0
cpll 7 19 800000000 0 0
cpll_aclk_perihp_src 0 0 800000000 0 0
...
pll_gpll 1 1 594000000 0 0
gpll 10 10 594000000 0 0
gpll_aclk_perihp_src 2 2 594000000 0 0
hclk_perihp 5 5 74250000 0 0
hclk_host1_arb 2 2 74250000 0 0
hclk_host1 2 2 74250000 0 0
hclk_host0_arb 2 2 74250000 0 0
hclk_host0 2 2 74250000 0 0
3. by default, G5[0] and G5[1] are enabled:
localhost ~ # mem r 0xff760314
0x000003e0
4. close the G5[1] (aclk_perihp_cpll_src), and plug/unplug USB ethernet cable,
the DUT still works well:
localhost ~ # mem w 0xff760314 0xffff03e2
localhost ~ # mem r 0xff760314
0x000003e2
plug/unplug, the work statue is ok
5. close the G5[0] (aclk_perihp_gpll_src), , and plug/unplug USB ethernet cable,
the DUT will be crashed:
localhost ~ # mem w 0xff760314 0xffff03e1
localhost ~ # mem r 0xff760314
0x000003e1
plug/unplug, the DUT is crashed
Summary:
bit 1 - shows aclk_perihp_cpll_src_en
bit 0 - shows aclk_perihp_gpll_src_en
