1Device Tree Clock bindings for ATL (Audio Tracking Logic) of DRA7 SoC.
2
3The ATL IP is used to generate clock to be used to synchronize baseband and
4audio codec. A single ATL IP provides four ATL clock instances sharing the same
5functional clock but can be configured to provide different clocks.
6ATL can maintain a clock averages to some desired frequency based on the bws/aws
7signals - can compensate the drift between the two ws signal.
8
9In order to provide the support for ATL and it's output clocks (which can be used
10internally within the SoC or external components) two sets of bindings is needed:
11
12Clock tree binding:
13This binding uses the common clock binding[1].
14To be able to integrate the ATL clocks with DT clock tree.
15Provides ccf level representation of the ATL clocks to be used by drivers.
16Since the clock instances are part of a single IP this binding is used as a node
17for the DT clock tree, the IP driver is needed to handle the actual configuration
18of the IP.

28 * sun7i_a20_gmac_clk_setup - Setup function for A20/A31 GMAC clock module
29 *
30 * This clock looks something like this
31 * ________________________
32 * MII TX clock from PHY >-----|___________ _________|----> to GMAC core
33 * GMAC Int. RGMII TX clk >----|___________\__/__gate---|----> to PHY
34 * Ext. 125MHz RGMII TX clk >--|__divider__/ |
35 * |________________________|
36 *
37 * The external 125 MHz reference is optional, i.e. GMAC can use its
38 * internal TX clock just fine. The A31 GMAC clock module does not have
39 * the divider controls for the external reference.
40 *
41 * To keep it simple, let the GMAC use either the MII TX clock for MII mode,
42 * and its internal TX clock for GMII and RGMII modes. The GMAC driver should
43 * select the appropriate source and gate/ungate the output to the PHY.
44 *
45 * Only the GMAC should use this clock. Altering the clock so that it doesn't
46 * match the GMAC's operation parameters will result in the GMAC not being
47 * able to send traffic out. The GMAC driver should set the clock rate and
48 * enable/disable this clock to configure the required state. The clock
49 * driver then responds by auto-reparenting the clock.

417 * ________________________
418 * MII TX clock from PHY >-----|___________ _________|----> to GMAC core
419 * GMAC Int. RGMII TX clk >----|___________\__/__gate---|----> to PHY
420 * Ext. 125MHz RGMII TX clk >--|__divider__/ |
421 * |________________________|
422 *
423 * The external 125 MHz reference is optional, i.e. GMAC can use its
424 * internal TX clock just fine. The A31 GMAC clock module does not have
425 * the divider controls for the external reference.
426 *
427 * To keep it simple, let the GMAC use either the MII TX clock for MII mode,
428 * and its internal TX clock for GMII and RGMII modes. The GMAC driver should
429 * select the appropriate source and gate/ungate the output to the PHY.
430 *
431 * Only the GMAC should use this clock. Altering the clock so that it doesn't
432 * match the GMAC's operation parameters will result in the GMAC not being
433 * able to send traffic out. The GMAC driver should set the clock rate and
434 * enable/disable this clock to configure the required state. The clock
435 * driver then responds by auto-reparenting the clock.
